MAINTENANCE

Carburetor

The carburettor is equipped with fixed needles to ensure
the machine always receives the correct mixture of fuel
and air. When the engine lacks power or accelerates
poorly, do the following:
• Check the air filter and replace if necessary. When this
does not help, contact an authorised service
workshop.
Adjusting the idle speed
!
Start the engine and check the idling setting. When the
carburetor is set correctly the cutting blade should be still
while engine is idling.
• Adjust the idle speed using the T screw. When an
adjustment is necessary, first turn the screw clockwise
until the blade starts to rotate. Now turn the screw
anti-clockwise until the blade stops rotating.
Rec. idle speed: 2700 rpm
CAUTION! Contact your dealer/service
workshop, if the idle setting cannot be
adjusted so that the blades are
stationary. Do not use the machine until
it has been properly adjusted or repaired.
